Abstract: An information processing apparatus according to an embodiment of the present disclosure includes a real image signal generator, a CG signal generator, and a. transmission section. The real image signal generator modulates real image data by a first modulation scheme to thereby generate a real image signal. The real image data is obtained by imaging of a surrounding environment. The CG signal generator modulates CG data by a second modulation scheme to thereby generate a CG signal. The CG data is obtained on the basis of data obtained by sensing of the surrounding environment. The transmission section transmits the real image signal and the CG signal to n external device by wireless communication.
